Heat and Temperature

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three types of heat transfer?

Back

Conduction, convection, and radiation.

Front

What is conduction?

Back

When heat transfers from objects that are touching.

Front

What is convection?

Back

The transfer of heat through a fluid (liquid or gas) where warmer parts of the fluid rise and cooler parts sink.

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, such as light.

Front

What is temperature?

Back

A measure of the average amount of kinetic energy of the particles in an object.

Front

What is a thermal conductor?

Back

A material that allows heat to pass through it easily.

Front

What is a thermal insulator?

Back

A material that does not allow heat to pass through it easily.

Front

How does thermal energy affect particle movement?

Back

When thermal energy is added, particles move more rapidly and at an increased distance from each other.

Front

What happens to a substance when it is heated?

Back

Its particles gain energy, move faster, and may spread apart.
